    of nowhere and claim 50% more compression than hevc.

    HD video can be live encoded below 500 kbits/s without loss of picture or viewing continuity

    Sure.......

    Hmm...only press so far is the company's own news releases and others mirroring/parroting it.

    I'll believe it when I see direct head-to-head A/B comparisons (with known/common sources).
    More likely that Daala would come to fruition, IMHO.
    Also, Daala is FOSS, while Perseus is $$ proprietary (and seemingly hardware-based, ATM), so I'd prefer Daala for that reason as well.

    Always again amazing when groundbreaking new technologies are announced around the 1st of April.

  6. This article have more information.

    http://www.digitaltveurope.net/346362/v-nova-promise-video-at-audio-bitrates-with-revo...on-technology/

    '' Sky Italia’s head of engineering and innovation Massimo Bertolotti was on hand at the launch event to provide details of what the company has been working on. “Contribution was the perfect ecosystem where a new technology can be tested,” he said. Sky previously used JPEG2000 for contribution but is switching to Perseus, with a target date of June for completion of the transition.

    V-Nova demonstrated contribution output at 300Mbps at the event, compared with 1Gbps for JPEG2000, based on a live uncompressed 12Gbps feed. It also showed the same live feed in UHD at 8Mbps compared with a 21-27Mbps HEVC feed. Another demo showed UHD Profile D recorded content at 8Mbps, compared with a HEVC feed at 21Mbps.

    Actmann said that V-Nova’s patents were “clean”. V-Nova plans to license the technology and has no current plans to make it available for standardisation. The company believes that the step-change in compression it offers will be compelling to broadcasters and video service providers.''

  7. Broadcom has provided some more detail on its involvement with V-Nova

    http://www.v-net.tv/broadcom-gives-a-few-more-details-about-its-work-with-perseus-codec

    Broadcom says it supports V-Nova with its reference design and software environment, and adds that, “PERSEUS implementations are wholly driven by V-Nova.”

    Asked how it is possible that a codec with such a dramatic claimed compression performance improvement does not require a new generation of decode chipset, Broadcom replied: “PERSEUS implementations will be driven by V-Nova through a software implementation of their algorithm, the details of which V-Nova is in the best position to provide. Broadcom does not receive or deliver V-Nova’s software code.”

    The SoC provider added: “Regarding currently field-deployed set-top boxes (and some in development), generally speaking you can expect CPU power to be critical to support PERSEUS.”

    Asked if it will produce a new generation of chipsets with PERSEUS support (even if PERSEUS works on older boxes), and whether there is anything be gained from this (like maybe better performance for PERSEUS on a new generation of chipset or box), Broadcom answered: “We do not currently have dedicated hardware acceleration specific to PERSEUS in our silicon.”

  8. Total bullshit! How many time we had read in past about revolutionary codecs which were supposed to be better than h.264 by magic 50%?
    Even today x265 (HEVC) is not 50% better than x264 (AVC). In most cases it is only about 25% more efficient than AVC.

    I'm too old for this repeating scam over and over again.

    Well, the news feeds are continuing into April 2, so I kind of doubt that.

    The 'next' codec is always advertised to be miles better with the argument that 'our eyes do not notice it' because of 'psycho babble'. Then of course when we seen 100+ videos we start to notice the new compression artifact misery.

    More than a decade ago Xvid was introduced as this wonderful 'virtually unnoticeable artifact containing' revolutionary codec, now in 2015 I cannot even watch Xvid without being constantly annoyed about the idiotic regularly shaped artifact blocks.

  12. Apparently Perseus codec is totally based on artificial intelligence and machine learning without using old technique like dct for compression interestingly last month another company magic pony technology announced a pre-compression algorithm based on machine learning that give any codec 70% more gain .look like machine learning are becoming a exciting new field for video compression .

    I wonder if the whole website appeared the same day. Can that be checked? Maybe using the Google keyword history.

    P.S.: Google Trends: Neither "v-nova" nor "perseus codec" have been searched often enough ever.

    P.P.S.: Address is "1 Sheldon Square"; Sheldon ... Sheldon Cooper ... no, I don't watch sitcoms.

  15. Utter bullshit. On April 1st, 2006 we heard about a superior object-based codec called EuclidVision by EuclidDiscoveries which claimed a typical DVD rip would be 50MB at the same quality 700MB DVDrips are (they didn't say Xvid or x264).

    Before that there was a similar claim by Pulsent Technologies of a revolutionary object-based codec.

    What a coincidence, eh? All of these seem to happen on April Fools day. On the net they're called trolls, IRL they're called patent applicants.

  18. Does anyone here know something about compressive sensing algorithm for video compression ? look like v-nova is based on that technique.

    here is a paper about technique

    Even if their "claims" come close to the truth, this is a PROPRIETARY, hardware-based technology that the company seems to be intent on LEASING (both encode & decode). No free software decoder (even with much beefier PC), no SAAS encoder even. Licensing? Until much of that changes, it won't help you & me for squat! Might as well ooh & aah about a more efficient satellite transponder.

    Those first 3 partners are just what I expected, but the addition of visualon must mean the inclusion of software (decoder) licensing, which is encouraging.

    Did anyone save a copy of the Hitachi PDF ?

    http://www.hds.com/assets/pdf/p-link-low-latency-video-gateways.pdf

    Seems to of gone missing from the Hitachi website after NAB2015. Searches of HDS.com with V-Nova, perseus, p-link don't turn up anything currently. Saw their demos at NAB2015, talked to a couple of their guys at the show. Looks and sounds promising for BW reduction at contribution and distribution level, but we'll see if real world products pan out.

    Cheers.

  26. ... at bitrates that for visually lossless video quality are typically 2.5x to 3.5 lower than the bitrates required by JPEG2000 (translating into 60-70% bandwidth savings)
    Okay now the marked shifted from HEVC to JPEG2000 and only targeting the visually lossless compression scenario.
    -> So the main question will be: Are they faster than JEPG2000 (which is used for such transmissions instead of HEVC and H.264 because it is faster on the compression side -> less latency) during compression?

    Interview with the developers: h.260 h261 h262 h263 h264 h265 re all based on the ideas and concepts of the 1970s.

    It will have much better compression than HEVC, and faster than h264.

    If we have to be honest.....
    well, all operating systems /programming languages /software /firmware currently-available...
    still are based on "the ideas and concepts of the 1950s /1960s /1970s"
